A member of the health care team is researching the etiology and pathogenesis of a number of clients who are under his care in a
hospital context. Which of the following aspects of clients' situations best characterizes pathogenesis rather than etiology?A. A client who has been exposed to the Mycobacterium tuberculosis bacteriumB. A client who has increasing serum ammonia levels due to liver cirrhosisC. A client who was admitted with the effects of methyl alcohol poisoningD. A client with multiple skeletal injuries secondary to a motor vehicle accident
The correct answer is B. A client who has increasing serum ammonia levels due to liver cirrhosis
Explanation:
Etiology is the study of origin or cause of any disease. Pathogenesis is the mechanism of causing disease by any pathogen. Pathogens use four-step to become pathogenic which are contact, colonization, invasion, and infection.
In pathogenesis the symptoms of disease is observed not the cause so in option B increasing serum ammonia level is the symptom of liver cirrhosis which characterize pathogenesis rather than etiology and in other option, only cause of a medical condition is described so the correct answer is B.
